Ran some sessions back to back at AutoClub Speedway this weekend, air scoops for transmission and differential passed the first track test. Most folks cannot run multiple sessions back to back but Instructor wrist band let me go and go a few back to back sessions to do our first testing of trans and diff temps in high ambient conditions. Trans peak temp was 219, the diff just 190....with ambient at and over 80F. Did just the morning but that's COOLER trans and diff temps than we ran for both when normally aspirated under similar conditions in May for just the morning, which means getting more air on the trans and diff is testing effective so far. It was a short day, jumped in our Supercharged RF for the second half of the day for a road trip (see RF thread for details). See pics of air scoops on prior pages of this thread.

Oil temps good and steady with our modified mounting of the Mishimoto Oil Cooler, back to back sessions and still 210 to 215 F. Coolant temps rock steady at 209 through back to back sessions, our triple pass CSF radiator continues to prove it is awesome.

Later Edit....my first version of this post noted what I figured was an Ecutek issue, but we now suspect our attempt to add an aftermarket intake is giving us some problems. So, going back to stock intake with the supercharger with more testing to come.

Great to know! A lighter and simpler solution than adding extra a coolers, and it will probably make more than enough improvement for many of us.

Just days to Laguna event and the motor is all in pieces again!

I really hate to retreat from our plans of E85 with the ported and flowed 'hyper flow head' that flows about 40% more air but we have learned that we are just too far off the specs of the other sensors, exceeding the MAF sensor limits constantly with resulting error codes and lumpy delivery, etc. Consulted with Edelbrock on our logs and what it would take to get the tune where it needs to be for this radically higher flowing head with E85, and though they agree it is possible, their opinion is the project would need a few weeks more of custom tune work...and that means we just do NOT have sufficient time to get it done before hitting the road for the MRLS event next Wednesday.

So, many hours more invested and we have yanked the hyper flow head. That created an issue of needing a stock head...and we did not have an unmolested head (my experiments with Skyactiv head flow have chewed up all our spare heads). A call to friends at Mazda and we learned no heads on the west coast. Okay, starting to get anxious....will this ND make the Laguna event next week?

A few more calls and thanks to some friends at Redline AutoSport we over night ship Florida to California a used head that reportedly has 9000 miles on it. Took it apart, quick clean up job, etc. The plan is get it all put together and back in the car and simply run the Ultrasafe CARB tune for the Laguna event. That's a big disappointment...likely end up about 200 hp like our RF instead of the 230+ that we hoped to get with the Hyper Head and E85 and the Longtube header. Bummed about it but time is too short to get it done now, so we will learn the limits of this kit with exotic head and E85 another time.

Awww! :(

Thank you guys for pushing the platform. You’ll make it work eventually. Good luck at MRLS!

Ahh...proper seats!

The factory leather seats are nice for slow cruise but driver fatigue on track days is high and I am tired of wearing knee pads to keep from bashing my knees trying to keep myself behind the wheel. Our Friends at 949 use the same seat, they posted at Miata.net that these 'fit' but their definition of 'fit' is perhaps unique to guys who think nothing of making the mods needed to get them installed. These are NOT plug and play! Plan on pulling back the covers and carving off about 1.25 inches from where the driver's seat would otherwise run into the trans tunnel...or use a mallet to move the trans tunnel a lot. And you pull back the covers and shave the shoulder wings down a little too. All looks good with covers back on but it took Rocky some serious work for install. These are amazingly comfortable for 'race' seats, 330mm measurement for hip space is generous for my 6'2 and 200 pound body. Using our PCI mounts with these I am about 1 inch lower with cushions installed. The cushions are held in place by velcro, on track days they rip out easily and that drops me about another inch.

Do you sit any lower in these? Depending on height, leg/torso ratio, and amount of hair -- tops can be mighty low.

About 1 inch lower with cushion installed, and if I pull that for track days about 2 inches below stock height.

Tour at Edelbrock today and the manufacturing process for these new supercharger kits. Not allowed to take pics of some things but the takeaway is that pretty much everything in the kit is made in-house at Edelbrock...that includes the blowers, intercoolers, etc.

Shown here 3d printed housing from the prototype process.

ND Miata Superchargers on shelf waiting for testing. EVERY blower is made here and EVERY blower is quality checked in fantastic detail and bench flow tested.

How much do the PCI seat mounts weigh?

Didn't weigh it separate. Did weigh the combo of the seat and mount against stock seat with mount...and this was just a little lighter, and once harness was added it was very close to even push.

DAY one of three day Mazda Raceway Laguna Seca Weekend!!!

L1.jpg


Today was test and tune day in preparation for the big event tomorrow. Chased some handling balance issues, too much oversteer to push the car confidently in the first session. Made shock and tire pressure changes and it was better in second session though back end was still too loose. Made rear sway bar softer and finally the car came good for balance in the third session. Power is 204 hp with the current tune on the best cold morning first lap, drops quickly to 190 range with repeated runs, standard everything and version of the CARB tune. I really want it FASTER, it's just not fast enough after driving our 300 hp supercharged 2007 but that car took years of development and it's going to take time here too. I really miss the highflow head we had on the car for Mazfest, which made more power (223+ hp) and additional torque you could really feel, so we will get back to getting the hyper head on the car so it is faster. Trans temps staying stable in same range we saw at MazFest, which is great news. What is not great news is that our Mishimoto Oil Cooler is NOT enough for supercharger, our oil temps spiked north of 250 once the day got hot and the sessions longer...and that's higher than we want. So, we will be working on several strategies....like getting more air through the front end and better oil cooler setup. More testing to come!

Zooming past the traffic on the front straight!

Doesn’t look like it slowed you down too badly, Brian. Haha!

Is the balance issue still because you’re tweaking for the new diff?

Yep, the OSGIKEN has a more aggressive lockup rate...and it's just 'too new' and tight. Been through this with their setups before, needs a few thousand miles to loosen up and then we will revert our settings somewhat.
